Nationwide Cooling Water Treatment Service
Cooling Water Treatment & Dosing
Scale, corrosion, contamination and other fouling will have a harmful effect on your cooling water system over time. These factors cause congestion inside your water system, reducing water flow and the cooling efficiency of your system.
What's more, these contaminants provide an ideal environment for microbes such as legionella, E. coli and many others. They can pose a serious health risk to the people who use your facilities.
They can cost you thousands of pounds in wasted energy every year, and they can damage the components in your plant.
Therefore, thoroughly cleaning and dosing your water system is essential. And proper water treatment can prevent the build-up of scale and other contaminants in the first place.
Effective Cooling Water Treatment
As water enters your system, it carries a number of contaminants that can harm your water system. This includes minerals, solids, chemicals, and microbes. Even oxygen is an undesirable element - it promotes corrosion within the system. Proper cooling water treatment can remove the majority of these contaminants before they get into your system.
The main goals are to protect your system against corrosion, control the formation of scale, and to prevent the growth of harmful microbes.
As cooling systems lose heat through evaporation, the result is a concentration of minerals and solids that do not evaporate. This makes cooling systems especially prone to a build-up of mineral deposits and suspended particles, leading to scale and fouling.
A controlled bleed off system can remove contaminated water and mix in fresh water, reducing the concentration of these minerals and particles. An automated system monitors your water and performs this action automatically.
Scale formation in heat exchangers and cooling towers reduces the thermal conductivity of piping and elements. This reduces the heat transfer, making the cooling less efficient.
Scale is a particular problem in hard water areas, but even soft water can cause scale when it is concentrated through evaporation.
The solution to scale is:
1: Dosing the water with a water softener.
2: Limit the water concentration with a controlled bleed-off and dilution system.
3: Add a scale inhibitor to the water.
4: For large industrial systems, you can dose the water with sulphuric acid to reduce the potential for scaling.
Corrosion is primarily caused by the presence of oxygen in the water. But there are other factors that can accelerate corrosion. For instance, if there are dissimilar metals in your water system, they will create a cell effect. It is similar to the chemical process inside a simple battery. The flow of ions from one metal surface to another causes corrosion.
When you identify the corrosive processes in effect, you can take control of the water chemistry to stop them. Therefore, it's essential for us to thoroughly examine your system to find the source of corrosion and fix it.
A cooling tower makes a perfect environment for microbes, including legionella. Beyond the obvious health risks, these microbes can cause a variety of operational problems for your system. This includes reduced flow, impaired heat exchange, and localised corrosion.
We use biocide additives to fight against the harmful actions of microbes.
Monitoring your water system requires regular testing. Water samples will reveal a huge amount of information about the state of your cooling system. Are there too many microbes? Is legionella present, or has some other deadly strain settled in? Is there corrosion? Chemical tests can even help to trace the source of leaks.
As you can see, effectively treating water for your cooling system is a delicate art. Our technicians are experts in all of the methods mentioned above, and many more besides. They can help you run your water system more efficiently, cheaply and safely.
